# A Union B (AUB) - Union of Sets Calculator

In algebra, union of 2 number sets is the set of elements in both Set A and Set B. For example, if A = {1, 3, 5, 7} and B = {1, 2, 4, 6} then A ∪ B = {1, 2, 3, 4, 5, 6, 7}. Simply combining all the elements of any two sets is called union of sets, represented by AUB, ie., A Union B.

The above algebra set theory calculator helps you to find the union of any 2 sets A and B (AUB).

Union of two sets is commutative i.e. if A and B are two sets, then A Union B (AUB) = B Union A (BUA)

Union of sets is also associative. If A, B, and C are three sets, then AU(BUC) = (AUB)UC
